Thanks a lot guys,
looks like there are -as usual- a gazillion options ;))
f = function(x, vars) x[complete.cases(x[vars]),] seems to be the
most appropriate in my case though.

Dear all,
I have two probably very easy questions:
(1) Is there a way to access certain variables by their string-based name
representation?
Example:
numbers <- c("one", "two", "three")
varname <- "numbers"
print(varname[2])
print(get(varname)[2])
(2) I need this functionality for a customized na.exclude() function that I
am building, which should only exclude rows that have NA in certain columns.
Maybe there is already a function which does exactly what I need, so I'd
highly appreciate if someone could point me there ;)
My current implementation looks like this:
naexlcude <- function(data, varnames)
{
for(v in varnames){
data = subset(data, !is.na(v))
}
data
}
f = function(x, vars) x[complete.cases(x[vars]),]
b
